## Root Cause

Mexican banks enforce a 15,000 MXN daily cash deposit limit for non-resident accounts under SAT anti-money laundering rules; exceeding this triggers automatic account freezing until documentation is provided

## Dead Ends

- **** — SAT's system aggregates all cash deposits across branches by CURP; splitting doesn't bypass the daily limit (90% fail)
- **** — This violates AML rules on third-party transactions; the friend's account may also be flagged for unusual activity (85% fail)
- **** — Banks are legally required to report all excess deposits to SAT; the account remains frozen until a tax declaration is filed (95% fail)
